Check Digit Verification of cas no

The CAS Registry Mumber 1435476-55-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,5,4,7 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1435476-55:
(9*1)+(8*4)+(7*3)+(6*5)+(5*4)+(4*7)+(3*6)+(2*5)+(1*5)=173
173 % 10 = 3
So 1435476-55-3 is a valid CAS Registry Number.

Free-amine-directed alkenylation of C(sp2)-H and cycloamination by palladium catalysis

Liang, Zunjun,Ju, Long,Xie, Yongju,Huang, Lehao,Zhang, Yuhong

, p. 15816 - 15821 (2013/01/16)

A new protocol for the palladium-catalyzed free-amine-directed alkenylation of C(sp2)-H bonds and cycloamination is described. Substituted biaryl-2-amines react with various alkenes, including electron-deficient alkenes, aryl alkenes and alkyl alkenes, to give the corresponding phenanthridines with exclusive regioselectivity. The use of α-branched styrenes leads to the formation of tricyclic compounds with a seven-membered amine ring. The method operates through a free-amine-directed alkenylation and a subsequent hydroamination cyclization reaction. Seven-membered cycloamination: A new protocol for the palladium-catalyzed free-amine-directed alkenylation of C(sp2)-H bonds and subsequent cycloamination is described (see scheme). Substituted biaryl-2-amines react with various alkenes to give the corresponding phenanthridines with exclusive regioselectivity. The use of α-branched styrenes leads to the formation of tricyclic compounds with a seven-membered amine ring. Copyright
